2.2e Class Activity: Finding Slope from Two Points
Calculate the slope of the following graphs:
Graph the following pairs of points. Use the graph to determine the slope.
Find the rise and run and slope of each line shown below. You will have to think of a way to use the coordinate points to find the rise
and run.
14. Graphing points can be time-consuming. Develop a procedure for calculating the slope without graphing each point.
Explain your procedure below. Show that it works for problems 1-4 above.
15. Discuss the methods for calculating slope without using right triangles on a graph. Write what you think about the
methods.
16. Now discuss the formula. m =
What does it mean? How does it work?
17. Filll in the missing information in the problems below. Use the empty box to calculate slope using the formula.
